So you did found the relevant PR with long audit trail and patches attached. You obviously should contact the author of the patches, Oliver Fromme, who is FreeBSD committer for some time (CCed). I agree that the thing shall be fixed finally. Skimming over the patches in kern/94772, I have some doubts about removal of POLLINIGNEOF flag. The reason is that we are generally do not remove exposed user interfaces.
